CHARLES GOODWIN, OF EAST PROVIDENCE, RHODE ISLAND;

ROTARY CHECK.

Application filed December 24, 1912.

To all whom it may concern:

Be it known that I, CHARLES GoonwIN, a citizen of the United States,residing at East- Providence, in the county of Providence and State ofRhode Island, have invented certain new and useful Improvements inRotary Checks, of which the following is a specification.

My invention relates to rotary checks intended for use in eyeglassholders and similar articles wherein a reel or other rotary disk membermoves in a casing or housing under tension of a spring and it is desiredto automatically check the reel relatively to the housing.

The essential objects of my invention are to effect the checkingoperation with certainty and facility; and to obtain these ends in asimple and inexpensive manner, and by means available in a minimum ofspace.

To the above ends my invention consists in such parts and suchcombinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification :-Figure 1 is a front view of an eyeglass holder embodying my invention,showing a portion of the front plate broken away, Fig. 2, a sideelevation of the same, Fig. 3, a section taken on line 50 c0 of Fig. 2,Fig. l, a section taken on line g y of Fig. 1, Fig. 5, a View similar tothat of Fig. 1 showing the device in released position, and Fig. 6, aside elevation of the modified form of my device partially indiametrical section.

Like reference characters indicate like parts throughout the views.

In the present instance my invention is illustrated as embodied in aneyeglass holder comprising a casing 1, to the back of which is fixed ajoint 2, a catch 3, for a pin tongue 4 mounted upon a pivot 5 in thejoint. The casing in the present instance comprises the back plate 7having a side wall or flange 8 provided with opening 9. The back plate 7is provided with a central perforation 10 to receive the reduced endportion 11 of a post 12, said reduced end forming a resultant annularshoulder 14 adjacent the lower end of the post. Integral or fixed to thepost is a cage-like structure comprising a perforated base 15- whoseperforation 16 permits the passage therethrough of the portion 11 of thepost and whose upper surface abuts against the shoulder 1 1 whereby thebody 15 of the cage Specification of Letters Patent.

is rigidly held in position against the back plate 7 by virtue of theriveted over end 17 of the post upon the rear face of the back plate 7.Interspaced upwardly extending arms 18 upon the periphery of the body 15complete the cage. The casing l is completed by a front plate 20 havinga mar ginal flange 21 frictionally engaging and overlapping the flange8, and provided with an opening 22 which registers with the opening 9.It will be understood that the casing may be of any preferred or desiredconstruction.

Journaled upon the post 12 is a reel 24. In the present instance thereel comprises a tubular hub 25 integral with a plate 26 which forms theweb portion of the reel and which is provided with a rearwardly directedmarginal flange 28. A lip 29 is cut from the web portion 26 of the reeland around this is the looped end 30 of a volute spring 31 whoseopposite end is looped as at 32 upon one of the arms or fingers 18. Thespring is inc-losed intermediate the flange 28 and the cage. The reel24: is completed by a cylindrical rim 3 1 fixed upon the flange 28 andhas outturned flanges 35 extending from its ends. The rim 3 1 issomewhat longer than the flange 28 so that a relative depression 28results in the outer face of the reel for a purpose to be hereinafterreferred to. A staple 37 is fixed in openings 38 and 39 in flanges 34:and 28 respectively. To this loop or staple is fixed the end link of achain or other flexible member 10 which is wound around the rim 3-1 ofthe reel or drum and passes through the openings 9, 22, of the casing.

The description thus far serves to set forth a convenient form of casingand reel in conjunction with which my check mechanism may be employed.The latter mechanism is in the present instance formed as follows: Fixedto the reduced front end 13 of the post 12 by friction or by rivetingthrough an opening 14: as at 45 or otherwise is the base portion a7 ofan upwardly curved pointed finger 18 whose concavity 19 forms a seat fora ball. Integral with or fixed to the front face of the web portion 26of the reel or drum, in any convenient manner, are two radially disposedarms 51 in alinement with each other, each being provided with cut awayor recessed portions 53 at their inner ends in a plane lower than theplane of the outer end portions 54, whereby a clearance is afiorded'thefinger as when the drum is rotated. Loose in the depression 28 in theouter face of the reel 24 are a plurality of balls 56 of sufficientlysmall diameter to roll freely in the depression, but of too greatdiameter to pass intermediate the outer plate 20 of the casing and therecessed surfaces 53 of the radial arms 51. These balls, which in thepresent instance are shown as four in number, cooperate with the finger48 to check or release the drum. As illustrating the operation of thedevice it will be noted that in Fig. 1 one of the balls 56 rests bygravity in the cavity of the finger and the second ball assists inseating the first in its position by virtue of gravity. The ball is soseated by the movement of the reel 24 shown by the direction of thearrow. To uncheck or release the drum the chain 40 is downwardly pulledwhereby the drum is rotated in the direction of the arrow as shown inFig. 5, whereupon the upper of the balls 56 falls downwardly, and theball that has been seated is pushed out of its seat by the approach fromthe rear of the second arm 51. After both balls have been thrown out amanual release of the chain 40 centrifugally throws all the balls in acircular course be yond reach of the finger 48 until the chain 40 iscompletely wound upon the reel. It will be noted that a single ball 56seated in the finger 48 is sufficient to successfully check and operatethe drum without a second ball resting upon it, but the second ball solocated is found to doubly insure perfect action. Obviously a number ofballs may be employed, either one or any number preferably desired. thatmy check is operated when the finger 48, 47 is fixed as is shown in Fig.6, by solder or otherwise, to the inner face of the outer casing plate20, in which case however the upper end portion 59 of the post 12 is ofcourse not riveted over, as at 45 in Fig. 4, but is cylindrical and fitsin the opening 44.

I claim 1. In a check device, the combination of a reel, a post uponwhich the reel is rotatably mounted, a casing inclosing the reel, afinger provided with a curved seat fixed relatively to the reel andadjacent the surface of the reel, radially disposed elevations upon theface of the reel, and balls loosely mounted upon the face of the reeloperable in pairs and having freedom of movement, and of greaterdimensions than the space between the finger and the casing of the reeland adapted to contact with the elevations.

2. In a check device, the combination of a reel, of a casing inclosingthe reel, a post upon which the reel is rotatably mounted extendingbeyond the face of the reel, a fin- It will be also observed,

and of greater diameter than the portions 5 of the elevations movablebelow the finger.

3. In a check device, the combination with a casing, of a post fixed inthe casing, a reel rotatably mounted on the post, radially disposedelevations upon the reel provided with recessed portions at their innerends, a finger. fixed to the post adapted to register in the recessedportions of the elevations and provided with a seat,and balls freelymovable intermediate the face of the reel and the casing and operable inpairs.

4. In a check device, the combination of a casing inclosing the reel,of'a post fixed in the casing, a reel rotatably mounted upon the post,elevations upon the face of the reel, a curved pointed finger fixed tothe post intermediate the reel and the casing and be yond theelevations, and balls operable in pairs freely mounted intermediate thereel and casing of a diameter greater than the distance between thecasing and the elevations.

5. In a check device, the combination of a casing provided with anopening, a post fixed in the casing, a reel rotatably mounted on thepost, a flexible member Wound upon the reel and extending through theopening in the casing, said reel being provided with a depression uponits face, radially disposed elevations upon-the face of the reel withinthe depression provided with recesses at their inner ends, a curvedpointed finger fixed to the post at such a distance as to permit therecessed portions of the elevations to move thereunder, balls operablein pairs loosely mounted in the depression and adapted to engage thefinger and the elevations when the reel is rotated, and spring means foractuating the reel.

6. In a check device, a casing, a reel ro-, tatably mounted therein,radially-disposed arms carried by said reel, a finger having aball-seat, and balls in pairs one of the pair adapted to be received insaid ball-seat and the other to rest upon the seated ball and togravitate therefrom as the reel is rotated to allow the other ball to beremoved from its seat by one of said radial arms.

In testimony whereof I have afiixed my signature in presence of twowitnesses.
